IMPROVED ICE-CREAM REFRIGERATOR.

'i'he Schedule referred to in these Letters Patent and making part of the same.

-Harri To all whom it may concern Be it known that l, CARL VIGNA'L, of the city of New York, in the county and State of New York, have invented a new and Improved Ice-cream Refrigerator;

,and I do hereby declare that the followiugis a full, clear,

and exact description thereof, which will enable others skilled in the art to make and use the same,'referencc heilig had to the accompanying drawing forming part of this specification.

The drawing represents a perspective view, partly A vessels the ice used in the preparation, otthe cream will quickly melt and be wasted." For large hotels and establishments in which several kinds of ice-cream must be kept in good condition almost continually, the ordinary devices are almost useless.v My improved refrigerator, A, is made in form of a box, of wood or other material, and contains four, more or less,vertical cylinders, BB, which may be made of galvanized iron or other non-corrosive material. The spacesbetween and around these cylinders B are filled with charcoal or other non-conducting material. The covers Ozot' the cylinders are also filled with non-con ducting material, as indicated at a., in the drawing.

' A pipe, b, carryiuga faucet, projects from the lower part of each cylinder B, vthrough the side ot' the box A, for the purpose of'A discharging the dissolved ice.

Into each cylinder B is or can be placed an ice-cream freezer, D, of suitable construction, with ice and salt or other freezing mixture packed around it. When he ice-cream has been prepared the cylinders are closed by the covers C and the top of the box A by the double wooden lids E E, so that the frozen mixture may retain its temperature for as long a time as possible. v

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- The ice-cream refrigerator, containing the cylinders B, which are surrounded with nonheat-conducting material, substantially as Set fort-l1.
